Potting Mixes

Ultragrow Potting & Podium Mixes

We’ve changed the game by redefining the soil and potting market.

From the very beginning in 1986 Centenary Landscaping Supplies has focused on supplying the very best range of soils.

It was then I developed our first blended soil known as Special Blend Garden Soil. At that time, Special Blend was so different to anything available on the market it became a top seller while I was advised no one would buy it.

Once again in 2018, we are working diligently with topsoil suppliers and manufacturers, soil scientists and industry professionals to expand our range and set new standards with waste-free soils and potting mixes.

Choosing a good soil is fundamental as it will make up the foundation of your landscaped gardens for many years to come.

After spending hundreds or thousands of dollars on plants or turf it’s essential to ensure that your investment is protected with the best possible start.

Now you can choose from our new UltraGrow Collection of exceptional science-based landscape soils and growing media free of liquid & green waste. This UltraGrow Collection is unique to Centenary and uncompromised in quality and performance so you can be confident that the soil you choose will really work.

The UltraGrow™ range of container mixes redefines bulk supplied growing media and offers a superior alternative to the low grade bagged material often comprised of inconsistent recycled waste products. The growing medium is the absolute foundation to a good plant health, making the UltraGrow Range the new benchmark in this space.
